Design and Preparation of Oriented Short Fiber Natural Rubber Composites

短纤维-橡胶复合材料具有独特的力学性能以及特殊的物理机械性能。在混炼的过程中加入短纤维,并使用一定的方法使其具有一定的取向结构,可以使得短纤维-橡胶复合材料具备不同的力学性能。本文通过改变短纤维的种类和份数,并选择合理的纤维取向方向,力图获得高性能的短纤维-天然橡胶复合材料,并测试了其拉伸性能、邵A硬度和DIN磨耗性能。结果表明,不同短纤维取向方式对短纤维-橡胶复合材料的结构与性能具有显著的影响。

Short fiber rubber composites have unique mechanical properties and special physical and mechanical properties.In the process of mixing,short fibers are added and a certain method is used to make the short fibers with a certain orientation structure,which can make the short fiber rubber composites have different mechanical properties.This paper tries to obtain high performance natural rubber composites by changing the variety and number of short fibers and choosing a reasonable orientation direction of fiber,and further testing its tensile properties,Shore A hardness and DIN abrasion properties.The results show that different short fiber orientations have significant effects on the structure and properties of short fiber rubber composites.
